Does Zicam shorten colds? Ultra RapidMelts' label gives no zinc amount

In one review, zinc lozenges shortened colds only above about 75 mg a day, a line drawn after the fact. The Zicam Ultra RapidMelts label names no zinc amount, so the box can't show if it gets near.

Zinc

The Zicam Ultra RapidMelts pack says they shorten colds, a claim made under the homeopathic route rather than one a regulator reviewed. In one review, five lozenge trials under about 75 mg of zinc a day came back empty, while those above it found colds roughly a fifth to two fifths shorter. That line was drawn after looking at the data, from five trials below it and eight above. The tablets list their zinc only in homeopathic notation, so nobody holding the box can tell whether they come close.

The findings behind this

1∿
ImmuneZinc lozenges under about 75 mg a day did nothing in any trial

Five trials tested lozenges under that mark and every one came back empty. Above it, the same review found colds running roughly a fifth to two fifths shorter.

★☆☆Contested — the evidence disagrees with itself, or the finding carries a caution. A caution or conflict always shows one star, however strong the sources are.CautionThe 75 mg line was drawn after looking at the data rather than set in advance, so it explains the same trials it came from. Five trials below it and eight above is a thin basis for a threshold. Both reviews behind it have the same single author, whose complaint is what got the competing Cochrane review withdrawn.Click to keep this openSupport immunityZinc

OtherThe best-known zinc cold tablet does not say how much zinc it has

Zicam Ultra RapidMelts is labelled homeopathically, so the pack names no quantity of elemental zinc. The trials that found an effect needed more than about 75 mg a day.

★★☆Single study — solid evidence, such as one good trial or a large observational dataset, but not replicated at the top tier.A label is a regulatory and marketing document, not evidence: the pack's stated purpose of reducing cold duration is a manufacturer claim made under the homeopathic route, not one a regulator reviewed. Nothing here says the product does or does not reach the dose the trials used, only that the label does not let you check. This is the oral tablet, a different product from the nasal gels that drew the smell-loss reports.Click to keep this openSupport immunityZinc
